Overview
The Mallory 03193890 is a Type FP aluminum electrolytic capacitor delivering 400µF capacitance at 150VDC working voltage. This classic metal-can component was widely specified in vintage tube amplifiers, industrial control circuits, and military electronics. Though Mallory has ceased capacitor production, the 03193890 remains in demand for restoration and maintenance of legacy equipment where original part authenticity or exact performance characteristics are required.
Key Features
- Capacitance: 400µF
- Working Voltage: 150VDC
- Type FP metal-can construction with twist-lock or solder-tab terminals
- Aluminum electrolytic technology proven in decades of industrial and audio service
- Used condition — tested and fully functional
- Direct replacement for original Mallory specifications in legacy equipment
Technical Specifications
Exact dimensional and environmental specifications for the 03193890 are available from Mallory’s archived technical documentation. Critical parameters include operating temperature range, case dimensions, and terminal configuration, which should be verified against the specific equipment manual before installation. The capacitor is designed for standard PCB and chassis mounting typical of vintage industrial and audio-grade electrolytic cans.
